Interrupt Priority Register (INTPRI)
INTPRI is a 32-bit readable/writable register used to set the priorities of IRQ[7:0] (as levels from
15 to 0). These settings are only valid for IRQ/
IRL7
to IRQ/
IRL4
or IRQ/
IRL3
to IRQ/
IRL0
when
set up as individual IRQ interrupts (IRQ7 to IRQ0 interrupts) by setting the IRLM0 or IRLM1 bit
in ICR0 to 1.

Set the priority of IRQ0 as an individual pin interrupt request.

Set the priority of IRQ1 as an individual pin interrupt request.

H'0
R/W
Set the priority of IRQ3 as an individual pin interrupt request.
15 to 12
IP4
H'0
R/W
Set the priority of IRQ4 as an individual pin interrupt request.
11 to 8
IP5
H'0
R/W
Set the priority of IRQ5 as an individual pin interrupt request.
7 to 4
IP6
H'0
R/W
Set the priority of IRQ6 as an individual pin interrupt request.
3 to 0
IP7
H'0
R/W
Set the priority of IRQ7 as an individual pin interrupt request.
Note: Interrupt priorities are established by setting values from H'F to H'1 in each of the 4-bit
fields. A larger value corresponds to a higher priority. When the value H'0 is set in a field,
the corresponding interrupt request is masked (initial value).
